CVE-2022-0151Network attack vector

Service interruption via dependency proxy purge requests

Published Jan 18, 2022 · Updated Aug 2, 2024

Denial of service in affected GitLab releases allows remote authenticated users to interrupt service via package deletion requests. The dependency proxy purge API marks cached manifests and blobs expired but does not reliably enqueue the limited-capacity cleanup workers that remove them. Exploitation requires permission to purge a group's dependency proxy cache; published sources do not identify the exact failure mode that interrupts service.
